Below are diagrams representing the molecules of three pairs of samples. For each pair, label one sample as “hotter” and the other as “colder” based on your interpretation of the diagrams and your knowledge of how temperature, speed, and kinetic energy are related. If you need to, you can refer to the key concepts posted on the classroom wall. When you have finished labeling the images, answer the questions below.
